WILLIAM JAMES, OF BROOKLYN, ASSIGNOR` TO THE NATHAN MANUFAC- TURING COMPANY, OF NET YORK, N. Y.

LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 442,321, dated December 9, 1890.

Application filed May 2l, 1890. Serial No. 352,621. (No model.)

To all whom it' may concern:

Beit known that I, WILLIAM J AMES, of the city of Brooklyn, Kings county, State of New York, have invented certain new and useful Improvements in Lubricators, of which the following is a specification.

This invention relates to certain new and useful improvements in sight-feed lubricators. It refers more particularlyto what are termed single-connected lubricators, in which the admission of steam into the con densingchamber of the lubricator and the delivery of the oil to the parts to be lubricated are effected by one duct or channel.'

The object of my invention is to increase the efficiency of such single-connected lubricators by simplifying their construction and manufacture.

The improven'ients will be more fully understood by reference to thc accompanying drawings, in which- Figure l is a longitudinal vertical section 0n line l l of Fig. Fig. 2 is a longitudinal vertical section on line 2 of Fig. I3. Fig. is.v a horizontal cross section on line 53 23 of Fig. 2, omitting brackets and connections.

A is the body of the lubricator, containing the oil, and is provided with a filler B, which when removed discloses an opening in the body through which the reservoir is lilled with oil.

O is an externally-threaded shank cast in one with the main body of the lubricator. By means of this neck the lubricator is connected to the main steam-pipe, steam-chest, or cylinder of a steam-engine in the ordinary wellknown manner, a valve being interposed between the neck O and the steam pipe, chest, or cylinder for the purpose ot controlling the admission ot' the steam to the lubricator.

D is the condensing-chamber, screwed to the top of the lubricator-body. Steam is conveyed into the condenser D from neck C by means of the pipe E, which is screwed into the condenser in such a way that an air-chamber is formed in the condenser above the horizontal branch of pipe E. The horizontal branch of pipeE is closed at the end, and a series of holes is provided, forming a spray and de- Iiecting the steam toward the inner wall of the condenser in a tine film, thereby effecting a thorough and rapid condensation.

F is a pipe conveying the condensed water from the condenser to near the bottom ot' chamber A, the admission of the water into the cup being controlled by valve G.

II is the waste-valve to drain the cup ot its contents when required.

I is the oil-pipe conveying the oil from the oil-chamber through nipple l, water-iilled glass L, and channels M and M into neck C.

In single-connected lubricators as heretofore constructed the pipe conveying the steam to the condenser generally has been located inside of the chamber, or, it' located outside of the condenser, has been connected with it at its top. In the first case the lubricator, as a rule, becomes too hot, whereby the tormation of a steady continuous feed prevented, while in the second case, when the lubricator has been left standing' under steam over night, for inst-ance, the condenser lled up to the very top and caused what is termed iu the art plugging, preventing the necessary circulation for the proper operation of the lubricator. By connecting the pipe E at the side of the condenser more or less air will accumulate above the tube, preventing the filling up of the condenser and effecting a drainage of the surplus condensation under more or less pressure proportionate to the quantity of the accumulated air.

The operation of the improved lubricator is as follows: Steam being admitted into condenser I) and condensing there, the resulting water of condensation passes down the pipe F int-o the reservoir A, the admission of the water being controlled by valve G. The water thus admitted into the reservoir A will displace the oil, which will doat on the water and enter the tube I. Upon opening the regulating-valve N the oil will pass in drops through nipple K, glass Il, and channels M and M into the duct C, and thence to the parts to be lubricated.

I am aware that a double-connected lubricator has been proposed into which the pipe leading the steam to the condenser entered the latter at its side, and I am also aware that a lubricator has been constructed provided IOO with a top and bottom pipe both entering` the condenser, the top of the bottom pipe being entering the condenser at its side and leaving,r an air-space above the point of entrance, the branch of the pipe which en ters the condenser being closed and provided with :L series of holes, Condenser D, reservoir A, water-pipe F, Valve G, Waste-valve II, regulating-valve N, nipple K, glass L, and ducts M and M', all arranged es and for the purpose speeied.

In testimony whereof I have hereunto sels` my hand this 19th day of May, 1890.
